I'm just trying to be helpful here, but for all of you guessing 10,000 and upwards... that's not possible. If the cards were "liquified", and occupied every space (no air between cards occupying space), then you could still only fit about 10,000 cards in there. Sorry, but it's just not possible, guys. Now don't go back and edit your posts, that would be serious cheating! I realize I edited mine, but I didn't actually change my guesses, I just said mine were only accurate if Mr. Bayme didnt' mess with the scale. I hope I'm not DQ'd because of that!
